WRENCH.

Application filed `May .11, 1922. Serial No. 560,067..`

T0 all whom it may concern:

Be it known that i, AmnnrGAnnAoL/i, a.

citizen of Poland, residing at last Hain- Vmond, inthe county of Lake'and State of Indiana, have invented certain new and useful Improvements in Wrenches, of `which the Yfollowing is a specification.

This invention relates to certain Anew and useful improvements in wrenches and has particular' reference to the provision of an improved format sliding adjustment wrench wherein the inner jaw is slidablymounted upon the rigid shank of an outer jaw.

Y An object of the invention is tolprovide efficient means for obtaining quick adjustment of the inner sliding jaw and for maintzrining such jaw in its adjusted position.

Another object is to generally simplify an improved sliding' jaw wrench whereby the same may meet with all of the' requirements for a successful commerciali use.

Still another object of the invention is to provide a removable and reversible double slidable inner jaw with means for maintaining the same-in adjusted position upon the shank of a rigid outer aw when either face of the inner jaw is presented to the surface of the outer jaw.

With lthe above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combinavtion and arrangement of the parts hereinafter morerfullv described,illustrated in the accompanying drawings, and polnted out 1n the appended claim.

In the drawings forming a part of this a lication and in which like desifrnatinof D t characters refer to corresponding parts throughout the several views:

Figure 1 is a view partly in section andl partly in side elevation of a wrench constructed in accordance with the present invention, A

Figure 2 is a front elevational view of the wrench shown in Figure 1,

Figure 3 is a sectional view taken on line III- lil of Figure 1,

Figure 4 is a view similar to Figure 3 taken on line IV-IV of Figure 1,

Figure 5 is' a fragmentary view showing the outer end of the shank in elevation and Y its rigid jaw in Vlongitudinal section,

Y portion 6 of the'shank.

Figure 6 is a sectional view taken in two planes as represented by section linesVI-VI 55 of Figure 1, i g Figure 7y is a developed elevational view of the latch for holding the outer aw against turning-movement on the shank, andV Figure 8 isa detail sectional view online` 60 VIII-VIII of Figure showing the screw j pin entering theslot in the reduced end of* the shankvfor swivelly connecting the outer jaw thereto.

symmetrical shank 5' preferably constructed of bar iron andhaving a reduced cylindrical portion 6 at its outer end'onto which 1s;

revolubly lit-ted a rigid outer jaw '7 having. 70' a single operating face 8,`the jaw 7` being provided with a socket for snug reception'of the reduced portion 6 as shown clearly in Figure 5. 'The reduced 'portion 6 of' the shank is provided with an annular groove as Z5 at 9 and a screw 10 is threaded transversely of the jaw 7 so that the inner endsof said screw engage in the groove 9 so as to re-` movably fasten the jaw 7 upon the reduced of the jaw 7' is provided with a recessV 11V opening into the socket in which Vthe reduced ortions 6 is fitted, and this socket 1s ycoverer by a sui-table plate 12 fastened in place by screws 13 or the like, the plate 12 85 being preferably of inwardly'dish form for;

a purpose which will presently .become apparent.

The recess 11 is reduced at its inne-r portion so to provide a shoulder against 90 which is seated a washer 14 through which is slidably disposed a small latch bolt 15 which also extends through the plate 12, and a helical spring 16 is provided between the washer 14 and pivot plate 12 surrounding); 95

the latch bolt- 15 so as to normally urge the latter into a suitable socket 17 provided in one side of the reduced portion 6 of the shank 5, the washer 14 being suitably fastened to the latch bolt 15 so as to move with 100 By dishing the cover plate 12, y

the latter. the latch bolt 15l may lie normally flush with or inwardly of the adjacent side face of the jaw 7 so as to not'be damaged accidentally and yet the latch bolt 15 is readily accessiblev 105 for being withdrawn whenever itis desired Y Referring Vmore in detail'to t-he several 65 views, thev presentV inventronfernbodies, a

The opposite'si'de 8 0 Y 15'niay be frail in nature as the saine merely acts to prevent rotation of the jaw 7 while the greatest strain is upon the vscrew Y10 which is utilized to hold the jaw 7 on the reduced portiony 6. l Y l e The shank 5 is provided with a series of uniformly spaced sockets in each edge thereof. and one socket in each edge is adapt? ed to be engaged by means of a pin 21 fixed to the outer end of an adjacent pivoted lever 1 22, one lever 22ibeing pivoted between suitable earsf23 at each edge of the jaw 19 upon a pivot pin 24kv as clearly shown in Figures 1 and 4. The pins 21 slidably extend through suitable openings in the edges of the jaw 19, so that they may engage in the sockets 20, and for convenience in inanipulation` as well as tofpermit making of the Ystructure as little' cumbersome as possible7 the levers 22 are disposed at an oblique 'angle't'o Ythe longitudinal axis of the shank v5 so as to lie with their inner ends iii-a plane to one side of said'axis of the shank as seen in Figure 2. ln other words, this permit-s the inner ends of the levers 22 to move inwardly toward each other past the elges of the shank 5 when the levers 22 are swung to disengage the pins 21 thereof from the socket 20.

' A spiralconipression spring 25 is disposed between and suitably connected to the inner ends of the levers 22 so as to normally separate these ends for yieldingly maintaining the pins 21 normally in the sock-et 20 of the shank 5, and it will be seen that by means ofV a double latching arrangement of this Vkind a very effective maintenance of lthe inner jaw in adjusted position is had.

InY operation, the jaw 19 may be released by pressing togetherthe inner ends of the levers 22 so as to release the pins 21 from movement on the shank.

the sockets 20 and while grasping the levers 22, the operator may force the jaw 1Q toward or from Vthe jaw 7 as desired. The levers 22 may then be released and the spring 25 will Y automatically swing the saine *so as to engage the pins 21 in the adjacent sockets 20, thus effectively securing the inner jaw 19 against Should one of the faces 18 of the jaw 19 become damaged, the other may be employed by releasing the latch bolt 15. through an outward pull thereon,

and then'the jaw 7 may be revolved on the reduced portion 6 of the shank for a'half revolution until the jaw is disposed with its face 8 overlying the outerjaw face 18. The latch bolt 15 is then released to engage the ad`acent socket 17 and said i aw 7 is .thus

effectively maintained in the position which it has beenr brought.v rlhis construe` Ytion is also desirable should the jaw 19 have two faces of different forms foroperating uponA different types of work, as is obvious. f

From the foregoing description, lit/.isfbeV lieved thatthe construction andA operation as well as the advantages ofthe present invention will be readily understood and appre Vfciated by those skilled in the art.

Minor changes maybe made witho t departing from the spirit and scope of the invention as hereinafter claimed. Y

Havingthus described the invention', what I claim as new is :d i Y A sliding adjustment wrench incltnling a shank having theouter end thereof reduced in cylindricalV form, an outer jaw having a socket in which the reduced portion of the shank is snugly revolubly fitted7 inc-ans carried by said jaw and engagingthe reduced portion of the shank to prevent detachment of the aw from the latter while'perinitting the revolution of' the jaw on said reduced portion5 and means to hold the'jaw against rotation'on said reduced portion whenV said jaw is positioned to extend from either edge of said shank, and a sliding inner aw have:`Y

ing opposed working facesto selectively cooperate with the revoluble outer jaw. g In testimony whereof l affix my signatureY 1 ALBERT GARlAC/Z.r
